The \(Y(4660)\)  was observed in association with \(Y(4360)\)  by the Belle Collaboration
in \(e^+e^-\rightarrow \psi (2S)\pi \pi \)  [1]}. Its assignment is still controversial
though by filling the lower states with some of these observed enhancements,
it leaves the \(\psi (5S)\)  as a possible option. However, it should be pointed out that
the \(S\) -wave open-charm threshold \(D^*D_2\)  is located nearby. Therefore, possible contributions
from the open-channel effects or dynamically generated state cannot be ruled out [2]}.
